Abstract
L'invention concerne un procédé pour produire un tuyau isolé comprenant un tuyau interne, une matière d'isolation et une enveloppe. Le procédé de production de l'invention concerne en particulier un processus de moulage de matière isolante sur le tuyau interne, qui comprend les étapes consistant à recouvrir le tuyau interne au moyen d'une enveloppe fermée dont les extrémités sont ouvertes, puis à introduire le tuyau interne recouvert de l'enveloppe dans un moule. La matière isolante est injectée à l'état liquide dans le moule entre le tuyau interne et l'enveloppe. Après le début de l'injection, la matière isolante à l'état liquide se dilatera et finalement se solidifiera. Pendant ces processus, l'enveloppe est pressée contre la paroi interne du moule.
